What does it mean that when I get tanned, all my black(could be dark brown) body hair on my legs turn completely to light blonde hair, while my upper body hair does not turn to blonde at all? Is this a trait that all Europeans have?

Hmm, maybe the exposure to the sun bleaches your hair a little bit. The head hair is often bleached in summer if it's exposed to the sun for a long time, so I'm supposing same happens to the body hair.
Its a simple genetic change, the same as when children have blond hair and grow up to have brown hair we go through these changes throughout our entire lives.
